You can not make a point tangent to X axis (nor to a circle's edge), that makes no sense and FreeCAD will not do it. Nothing in your imagine appears to be Tangent to anything.papyblaise wrote: ↑Mon Nov 23, 2020 2:53 pmWhat is your remarkthat is not right, you can not apply a tangent between a point and the circle edge in sketcher. You would use "point on object" constraint.
I place the point on the circle, then I made this point tangent to the OX axis, and the proof by the image is correct

that does not make any sense.papyblaise wrote: ↑Mon Nov 23, 2020 11:56 am or you place a point on each circle tangent to the circles and to an axis line
You appear to have used "point on object" constraint. But you say "Tangent", perhaps you don't know what Tangent means in English, perhaps its your trying to translate ... I don't know, but what you said is nonsense.
